BEFORE WE START ITS BASIC COMMON SENSE THAT ANY PLANET SHOULD NOT BE OVERPOPULATED...THE VEDIC PHYSOLOPHY STATES EVERYTHING SHOULD BE IN MODERATION...NOT TOO MUCH NOR NOT TOO LITTLE AND THIS APPLIES TO POPULATION...KEEPING IT UNDER CONTROL AND IN BALANCE...I have stated before one boy and one girl for each couple will keep population in order....The Shiva Purana gives you guidance on what you need to do in order to get a girl or a boy and following this you can have one boy and one girl ...enough you don't need to be selfish and greedy  

Now the side effects of a Planet Being Overpopulated:

1  Using more of the Planet resources.

2 Less peace as an Overpopulated Planet will have lots of people suffering from stress and anxiety leading to sickness, depression and unharmony.

3 More violence and a higher crime rate 

4 More children not looked after properly....leading to poor children suffering 

5 An unbalance of couples as some countries having more boys then girls and some countries having more girls then boys 

6  More noise, more rubbish and dirty places

7 overpopulation leading to revolutions as lots of people unhappy.

8 More wars.

9 Most overpopulation is due to foreigners coming to a country and breeding like rabbits just so that their children will get citizenship and use of good faculties...these couples are just selfish and greedy

Taking all this in consideration OVERPOPULATING A PLANET IS DANGEROUS

Now we find that Planet Earth is Overpopulated and it's become dangerous to live in as crime, violence and wars are on the rise. Most people are unhappy on this planet as a lot are under great stress and anxiety and fear and hence suffering....just see how many are on drugs ( medicine's ...pills and tablets ) which are really screwing them up not healing them in any way ..most people addicted to doctor's drugs some taking 5-10 pills daily AND MOST SUFFERING FROM SIDE EFFECTS 

NOW WHAT CAN BE DONE ???

A much better and humane way is to allow couples to have just two children each meaning just one boy and one girl and in the long run after a few years the population will start to balance out to normal for a planet ...not Overpopulated..not too many nor not too less.
